To all whom it may concern:

Be it known that I, THOMAS V. GARLOOK,

a citizen of the United States, residing at Custer city, in the countyof Custer and State of South Dakota, have invented new' and usefulImprovements in Liquid-Etc tractors, of which the following 1s aspeclficatio-n.

This invention relates to a liquid extractor particularly designed foruse in connection with gasolene and other storage and supply tanks forthe purpose of drawing off portions of the contents thereof.-

The obj eot of the invention is to provide a simple, reliable andeflicient device of this character which may be applied to the screw capof the tank opening for attachment therewith, and by means of whichvarious quantities of the contents of the tank may be readily andconveniently drawn off. Y

The invention consists of the features of tank of the characterdescribed showing the application of the invention, the plunger being atthe limit of its inward stroke. Fig. 2 is a sectional view through theextractor showing the plunger at the limit of its outward suctionstroke. Fig. 3 is a sectional view through the outer end of the suctiontube or cylinder and allied parts on an enlarged scale.

In carrying my invention into practice, I provide-a suction tube orcylinder 1 having a conical inlet end 2 provided with an intake opening3. Arranged for operation within said tube is a plunger 4: suitablyfixed to the inward end of a rod 5, to which is applied, at a point inproximity to said plunger, a stop member 6. The outer end of the tube 1is perforated or slotted for a portion of its length, as indicated at 7,and an extremity of said end of the tube is threaded and passes throughthreaded opening in a supporting member herein shown in the form of thescrew cap or closure 8 normally employed to seal an opening 9 in thetank. The projecting end of the tube orcylinder is closed by a screw cap10, and suitably ar: ranged and clamped between the aforesaid parts is awasher 11, of felt or other preferred material, which prevents leakageof the'contained liquid through the joint. The

outer v1 end of the plunger rod extends through the washer and cap 9 andis threaded to receive an'operating knob or handle 12. .The stop 6 is soarranged that it will contact with the cap 10 and limit'the outwardmovement of the plunger when the inner or front face of the plungerreaches a point just in advance of the perforated portion 7 of the tube.

In practice, it will beunderstood that the device is applied to the tankwith the closure 8 and hence is pendent or projects into the tank sothatthe intake 3 will be sub merged, whereby upon drawing the plungeroutwardly a vacuum will be produced withv in the tube in advance of theplunger, so.

that the tube will be filled with the gasolene or other liquid forwithdrawal, allowing a quantity. to be withdrawn on each operation in anobvious manner.

It will, of course, bev understood that through leakage or otherwise anamount of the liquid may be presentin the tube behind the plunger. Whenthe plunger is drawn upward, however, this liquid will be elevated anddischarged through the perforated portion 7 back into the tank, thusavoiding waste and obstruction to the motion of the plunger.

An extractor or draw-off device of the character described is simple ofconstruction and by the mode of application set forth may be applied togasolene or other storage or supply tanks in such a manner as to bereadily filled and withdrawn, and is easily applied and secured inposition through the simple adjustment of the cap 8 to seal the opening9. The device allows an amount of the gasolene or other liquid to bedrawn from the tank wheneverrequired, and its convenience in thisrespect will be appreciated. V
